What I did nslookup fakedomain.org.au,,,,the resolved ip address is 2xx.xxx.60.89
At work I typed in : http://2xx.xxx.60.89/cpanel into an address bar of a browser.
I was able to access cpanel for our website.
Now my question shared hosting will have all websites on the same IP, my case the ip address is 2xx.xxx.60.89,,,and this is called : " name based virtual host "
And since cpanel uses name based virtual host, why when I typed in http://2xx.xxx.60.89/cpanel,,,I was able to get to the cpanel of our website ,,,,,why didn't I get to a cpanel for a different website , because ip that I used was shared for many websites not only my website
